A brake device of a rotating motor is disclosed and includes a base, an upper plate, a sliding plate, a transmission component, a lining plate, a connection element, a planar plate and an elastic component. A rotating shaft runs through the base in an axial direction. The sliding plate is arranged between the base and the upper plate, and driven by the drive module. The transmission component is sleeved and fixed on the rotating shaft, and includes a sleeved peripheral edge, a limiting portion, and a perforation. The limiting portion is protruded outwardly from the sleeved peripheral edge in a radial direction, and the perforation is passed through the limiting portion along the axial direction. The lining plate sleeved on the sleeved peripheral edge is located between the sliding plate and the upper plate. The elastic component is arranged between the planar plate and the limiting portion.

An improved brake assembly having brake pads that are biased against a rotor using a caliper. Caliper mount brackets bolt to the caliper and hold the brake pads in position. The caliper mount brackets receive and retain replaceable contact plate inserts. The contact plate inserts contact and support the brake pads within the brake assembly. The contact plate inserts each have a first plate and a second plate that extends from the first plate at a perpendicular. The caliper mount brackets receive and retain the contact plate inserts in positions where each first plate and each second plate are positioned to support the brake pads when installed within the caliper mount assembly. The contact plate inserts are harder than the back plates of the brake pads. Accordingly, the contact plate inserts are not rapidly worn by the brake pads and can last much longer than do the brake pads.

A disc brake caliper and the body of an ABS system are mounted on a fork arm of a bicycle by means of a single adapter support that can be removably connected to the fork arm, and configured to removably support both the caliper body of the disc brake and the ABS system.

An electromechanical brake apparatus includes a housing supporting an inboard brake pad and an oppositely facing outboard brake pad for selective frictional contact with a rotor interposed longitudinally therebetween. The housing includes a mechanism cavity located longitudinally between the inboard pad and a motor having a motor output shaft. An adjuster ramp assembly indirectly receives torque from the motor. A spindle is operatively connected with the adjuster ramp assembly to indirectly receive torque from the motor therethrough. A leading ramp assembly is configured to transmit applied torque from the motor to the adjuster ramp assembly. The leading ramp assembly receives stepped-up torque from the motor via the motor output shaft and a ball thrust bearing at least partially located radially between the motor output shaft and an actuator ramp of the leading ramp assembly.
